Top quark FCNC decays and productions at LHC in littlest Higgs model with T-parity

Han,X; Wang,L; Yang,JMSubjects:

In the littlest Higgs model with T-parity (LHT) the newly introduced mirror quarks have flavor-changing couplings with the Standard Model (SM) quarks and may enhance the flavor-changing neutral-current (FCNC) top quark interactions which are extremely sup |

We examine the lepton flavor-changing processes in R -parity violating MSSM. First, we update the constraints on the relevant R -violating couplings by using the latest data on the rare decays ? i → ? j γ . We find that the updated constraints are much st |

Yukawa corrections to top pair production in photon-photon collision

Li,C; Yang,J; Zhu,Y; Zhou,HSubjects:

The O(αmt 2/mW 2)O(αmt 2/mW 2)O(\alpha m_t~2/m_W~2) Yukawa corrections to top pair production in photon-photon collision are calculated in the standard model (SM), the general two-Higgs-doublet model (2HDM) as well as the minimal supersymmetric model (MSS |

Supersymmetric electroweak corrections to single top quark production at the Fermilab Tevatron

Li,CS; Oakes,RJ; Yang,JMSubjects:

We have calculated the O(αewMt 2/MW 2)O(αewMt 2/MW 2)O(\alpha_{ew} M_t~2/M_W~2) supersymmetric electroweak corrections to single top quark production via qq?′→tb?qq?′→tb?q\bar q' \to t\bar b at the Fermilab Tevatron in the minimal supersymmetric model. Th |

Subjects:

We evaluate the supersymmetric (SUSY) electroweak corrections to the effect of parity nonconservation in qq?→tt?qq?→tt?q \bar q \to t \bar t production at the Fermilab Tevatron predicted by the Minimal Supersymmetric Model (MSSM). We find that the parity |

Supersymmetric QCD corrections to single top quark production at the Fermilab Tevatron

Li,C; Oakes,RJ; Yang,J; Zhou,HSubjects:

We evaluate the supersymmetric QCD corrections to single top quark production via qq?′→tb?qq?′→tb?q \bar q'\to t \bar b at the Fermilab Tevatron in the minimal supersymmetric model. We find that within the allowed range of squark and gluino masses the sup |

Virtual Effects of Split SUSY in Higgs Productions at Linear Colliders

Wang,F; Wang,W; Xu,F; Yang,JM; Zhang,HSubjects:

In split supersymmetry the gauginos and higgsinos are the only supersymmetric particles possibly accessible at foreseeable colliders like the CERN Large Hadron Collider (LHC) and the International Linear Collider (ILC). In order to account for the cosmic |

Top-quark FCNC Productions at CERN LHC in Topcolor-assisted Technicolor Model

Cao,J; Liu,G; Yang,JM; Zhang,HSubjects:

We evaluate the top-quark FCNC productions induced by the topcolor assisted technicolor (TC2) model at the LHC. These productions proceed respectively through the parton-level processes g g -> t c_bar, c g->t, c g -> t g, c g -> t Z and c g -> t \gamma. W |

Higgs-pair production in littlest Higgs model with T-parity

Wang,L; Wang,W; Yang,JM; Zhang,HSubjects:

The Higgs-pair production process at the CERN Large Hadron Collider (LHC), which will provide a way to test the Higgs boson self-coupling, may be sensitive to new physics. In the framework of the littlest Higgs model with T-parity, such Higgs-pair product |

R-parity violating effects in top quark FCNC productions at LHC

Cao,J; Heng,Z; Wu,L; Yang,JMSubjects:

In the minimal supersymmetric model the R-parity violating top quark interactions, which are so far weakly constrained, can induce various flavor-changing neutral-current (FCNC) productions for the top quark at the Large Hadron Collider (LHC). In this wor |
